I downloaded the script archive. Unpacked it to desktop. Read the readme. Double clicked it and nothing! I tried right click and no choice to 'open in terminal'. I tried manually opening it in a terminal and I get 'sh: Can't open 3in1.sh"
I checked the permissions and it looks like I don't need to sudo but I tried that anyway.

Please give me some information. What version of Kubuntu are you using? Secondly, is this all you did? What were the exact steps you preformed?

Yes that is all I did I am using ubuntu 64bit feisty.
My follow up post is what I did after to try to get it to run.

I had to update the script. Try the new one please. Please dont rename it. Navigate to the directory and use ./3in1 to start it. If the choosing feisty will not install it, try Edgy. The script is the same except 1 package and that should auto update.

Very useful script. My only qualm is with the difficulties associated with making the new browser the default one.

I started out with swiftweasel32, and set it to be the default in my preferred applications dialogue. While it opens links from the desktop ok, It wouldn't work with other applications that needed to open a browser, however, so I switched to firefox32, with the same results.
